TERM 1
body mechanics
DEFINITION 1
coordinated efforts of musculoskeletal and nervous systems
to maintain balance, posture and body alignmentused for
lifting, bending, moving and daily activities
TERM 2
body alignment
DEFINITION 2
relationship of one body part to anotherBody alignment is the
optimal placement of the body parts so that the skeletal
bones are efficiently used, so the muscles have to do less
work for the same effect.
TERM 3
body balance
DEFINITION 3
achieved by a low center of gravity and enhanced by posture
TERM 4
coordinated body movement
DEFINITION 4
must overcome an object's weight and be aware of its center
of gravity
TERM 5
friction
DEFINITION 5
rubbing together or resistance when a moving body meets a
surface, often when turning a patient you will create friction
with the bed.

DEFINITION 40 A medical error is a preventable adverse effect of care, whether or not it is evident or harmful to the patient.Inaccurate prescribing, wrong medication, route and time, extra doses or failing to administerReporting: written report within 24 hours of occurrenceComparison of meds taken at home and prescribed when in a health care setting

Accucheck errors

Finger not cleaned completely, squeezing finger too hard to obtain blood specimen, cleaning finger with alcohol, failure to cover the test strip completely, ignoring low battery warning, hypovolemic patient, physiological changes include out of range hemoglobin or uric acid levelTight glucose control equals better outcomes, in hospital should range between 90-180 mg/dl TERM 47

Proper Accucheck procedures (pt. 1)

DEFINITION 47 Use standard precautions (wash hands, wear gloves)When cleaning meter, use leach wipes or anti-germicide wipes when meter is contaminated, avoid wiping LCD windowFor isolation patients, place handheld in plastic bag with only test strip exposed, wipe meter down after use TERM 48

Proper Accucheck procedures (pt. 2)

DEFINITION 48

  1. Wash patient finger with soap and water2. Choose site on the side of finger pad3. wipe away first drop of blood to reduce tissue fluid contamination4. touch 2nd drop of blood to the edge of yellow window (not top-capillary action) no yellow should be visible (can reapply in 15 seconds) TERM 49

Blood sugar

DEFINITION 49 If too low (under 80) treat and verify resultsCritical values are anything less than 40, treat, verify results, notify MD, document TERM 50

Rule of 15 with diabetes

DEFINITION 50 If patient is symptomatic and glucose is less than 80, give 15g carbs (4 oz juice/non-diet soda, 8 oz milk, 3 graham crackers, 15gm glucose gel)If patient cannot take oral give IV d50 25 ml, repeat test in 15 min.If patient is symptomatic, treat then retestIf patient is asymptomatic, retest then treat hypoglycemia

Cardiopulmonary Physiology

Ventilation: movement of air in and out of lungs, occurs in the alveoliRespiration: exchange of O2 and CO2Diffusion: movement of gases between air spaces and blood stream, CNS must be intact for this to occurPerfusion: movement of blood into and out of lungs to organs and tissues...heart pumps blood to tissues TERM 52

Pulmonary Anatomy

DEFINITION 52 2 lungs, R lung has 3 lobes and is more prone to aspiration pneumonia, L lung has 2 lobes, trachea, R and L main stem bronchus, bronchioles, alveoli TERM 53

Ventilation

Regulators

DEFINITION 53 Neural regulators: CNS sends signal to chest wall to control rate, depth and rhythm of ventilationChemical regulators: CO2 and H+ affect rate and depth of ventilationOxygen transport: influences ventilation and perfusionCarbon dioxide transport: dissolved in plasma, carbamino compounds, bicarbinate TERM 54

Pulmonary Alterations

DEFINITION 54 Hypoxia: inadequate tissue O2 at a cellular level, could be caused by anemia, will see peripheral cyanosis (blue lips, fingers, toes)Hypoventilation: inadequate ventilation to meet body's demand, can be caused by CO2 poisoning, head trauma or hyperventilatingHyperventilation: increase in respiratory rate, seen in fever, anxiety, acid-base imbalance, causes light- headedness and tachycardia TERM 55

Regulation of blood flow (pt. 1)

DEFINITION 55 Afterload: resistance of ejection of blood from left ventricle of heart into the aorta that the heart must overcome (resistance by aortic pressure)Cardiac Output (CO): amount of blood ejected by left ventricle each minute Myocardial contractility: ability of heart to squeeze blood from ventricle before the next beatPreload: amount of blood at the end of ventricular diastole (just before it contracts)

A Fib (atrial fibrilation)

AFib (atrial fibrilation): the most common electrical disturbance of the heart, irregular quivers as opposed to full contractionCan lose 20-25% of blood that would fill ventricle affecting CO and possibly BP, stagnant blood sitting in atrium can lead to clot formation TERM 62

Circulatory System Function

DEFINITION 62 Delivers oxygen and nutrients to support cellular lifeRemove waste products and deliver them to lungs and kidney for excretionPumping action of heart supports this sytem TERM 63

Factors affecting oxygenation (pt. 1)

DEFINITION 63 Decrease in O2 carrying capacity: reduced hemoglobin, carbon monoxide poisoning, anemiaIncreased metabolic rate: hypercapnia (too much CO2), hypoxemia, fever, pregnancy, wound healingDecreased oxygen concentration: obstruction, decreased environmental oxygenChest wall movement: musculoskeletal abnormality, nervous system disease, traumaPremature infants: diminished surfactant, lung collapse TERM 64

Factors affecting oxygenation (pt. 2)

DEFINITION 64 Infants and children: likely to put things in the mouth that they can aspirate or obstruct airwaySchool age/ adolescent: 2nd hand smoke and pregnancyYoung/Middle-aged: Smoking, poor diet, lack of exercise, high stressOlder adults: chronic illnesses, coronary artery disease, heart disease TERM 65

Lifestyle Factors

DEFINITION 65 Nutrition/hydration: high fat (blocks arteries), high salt (increases BP and HR)Cigarette smoking: nicotine vasoconstricts (possible DVT), destroys cilia in respiratory tract, cancer, asthmaExercise: you need it! Decreasses stress, deeper breaths, lowers HR and BPSubstance abuse: ETOH/drugs, infections, sepsis, HIV/AIDSEnvironmental factors: urban settings (smog, air pollution), old homes (asbestos, lead paint)

Abnormal Chest Wall

Movement

Retraction (patients lose weight because they cannot breath and don't want to eat)Paradoxial breathing/flail chest: left side in and right side out, vice-versaIncreased anteroposterior diameter: barrel chest (COPD and emphysema) TERM 67

Pulmonary Acute Care

DEFINITION 67 Dyspnea management: medications, oxygen therapy (need Rx), physical and psychosocial techniquesMaintenance and promotion of oxygenation: oxygen supply, methods of oxygen delivery, hydration, humidification, nebulizationNasal cannula: 2-6L/min 24- 25% O2Venturi mask: depends on setting, usually 24-60% O2Simple mask: depends on O2 flow, usually 40-60% O2Non- rebreather mask: as close to 100% as you can get TERM 68

Coughing techniques

DEFINITION 68 Cascade: series of coughs througout exhalations, slow deep breath in and slow deep breath out to produce coughHuff: while exhaling open the epiglottis by saying "huff", deep breath in and hard exhale saying "huff"Quad: push the diaphragm inward and upward for very weak patient's deep breath in, push on diaphragm in and up to create pressure for harder cough TERM 69

Suctioning techniques

DEFINITION 69 anything that goes through the trachea must be sterile technique, at most 15 seconds but in real life usually only 10 seconds, use intermittent suctioning TERM 70

Artificial Airways

DEFINITION 70 Oral: used after surgery of OD patient's to keep tongue from blocking airwayTracheal: used for a tracheotomy
